This is a mock fantasy book cover, set in the Forgotten Realms universe, that I did on commission.
The client wanted something that was akin to a Star Wars movie poster with characters sprinkled throughout the image. The blue character, Ningal, is some sort of important leader in the country of Unther. The other famous character in the image is Tiamat -- she's in the upper right corner. She's a dragon deity in cloaked in human form. The client wanted her depicted as a sort of spunky teenager girl.
During the process of creating this picture I worked out a design for each character before combining them into the picture. I'll post the design sheet up on my Quasieducational blog
